WOKING, England â The 2014 McLaren P1 is not about launching a new, hyper-exotic carbon-fiber supercar. It’s not a Pagani, nor is it a Spyker or a Mosler. It’s certainly not a Vencer, a Mazzanti, a Saker or any of those odd cars of questionable provenance that make it to the floor of the Geneva motor show. And it’s not a Lamborghini, although like Lamborghini, the P1′s maker has 50 years of building cars under its belt — in this case, mostly for Formula 1 and CanAm.
